Table REF  shows a comparison of results for the two best performing Raw PC-DARTS systems to that of the top-performing systems reported in the literatureNumber of learnable parameters and the decomposed EER results for Res-TSSDNet and LCNN-LSTM-sum were obtained using open-source codes available online. Those for ResNet18-GAT and RawNet2 were provided by the authors of [1]}, [2]}.. Among the illustrated systems, four operate upon raw inputs, including the top two systems, the first of which is the Res-TSSDNet system reported in [3]} and the second of which is the proposed Raw PC-DARTS. The fourth system which operates on the raw waveform is the RawNet2 system reported in [1]}. It also uses a first layer of sinc filters, GRU and fully connected layer for embedding extraction.
